Perez didn't factor into the decision Sunday against Milwaukee, allowing one run on two hits and two walks across five innings. He struck out six.

Perez's outstanding stretch of play continued Sunday, as he allowed fewer than three runs for a fifth consecutive outing. He's allowed fewer than four hits in all but one of those appearances. In nine starts this season, the 22-year-old has a 3.07 ERA and a 46:15 K:BB across 44 innings. He's tentatively scheduled to face the Cardinals his next time out.

Senga allowed three runs on four hits and five walks while striking out three over five innings in a no-decision versus the Giants on Sunday.

Senga had trouble finding the strike zone, throwing just 55 of 92 pitches for strikes. He has now allowed seven runs with a 12:10 K:BB over 12 innings across three starts since returning from a month-long absence due to a hamstring injury. Overall, his 2.00 ERA remains elite, but it's backed by a 1.21 WHIP and 82:41 K:BB through 85.2 innings over 16 starts, which suggest he's had more than his fair share of good luck. Senga is tentatively projected to make his next start at home in a rematch with the Giants.

Singer (8-8) yielded a run on three hits and a walk over 7.1 innings Sunday, striking out eight and earning a win over the Rays.

Singer was outstanding Sunday, rolling through seven shutout frames before Taylor Walls knocked a solo shot in the eighth. Singer threw 67 of 97 pitches for strikes and forced 16 whiffs, tying his season best. It was his first scoreless start since his season debut March 31. His dominant outing snapped a 0-4 skid over his previous six appearances. During that losing streak, he posted a 6.18 ERA. Singer dropped his season ERA to 4.60 with a 101:43 K:BB across 109.2 frames. His next outing is projected to be at home against Atlanta.

Gallen (7-12) allowed four runs on five hits and a walk over six innings Sunday, striking out five and taking a loss against Pittsburgh.

Gallen ran into some trouble early, allowing a run in the second inning and two in the third. Arizona couldn't bring a run home against Paul Skenes and the Pirates' bullpen, leading to Gallen's third consecutive loss. Gallen has given up at least four runs in seven of his last nine outings, registering a 6.24 ERA during that span. His season ERA is up to 5.60 alongside a 121:47 K:BB through 127 frames. Gallen's name has been floated around as a potential trade piece, but he's currently projected to take the mound on the road against the Athletics next weekend.

Skenes (6-8) yielded three hits and a walk over six shutout frames Sunday, striking out nine and earning a win over the Diamondbacks.

Skenes was his usual dominant self in Sunday's victory and turned in his second straight scoreless outing. The only real threat he faced was in the fourth inning when Arizona had runners on second and third with one out, but Skenes retired the next eight batters consecutively to end his day. He tossed 62 of 99 pitches for strikes and generated 20 whiffs, including seven with his sweeper and six with the fastball. Skenes now owns a ridiculous 1.83 ERA with a 146:32 K:BB through 133 frames. In his final eight starts before the All-Star break, he went 0-3 despite a 1.77 ERA, but he has earned a win in each of his two outings since. Skenes has produced an unreal 1.28 ERA over his last 14 appearances (84.1 innings). He's lined up to start in Colorado next weekend.

Wheeler (9-4) took the loss Sunday against the Yankees, allowing four runs on five hits and two walks over 5.2 innings. He struck out eight.

It's the first time since May 29 that Wheeler's failed to make it through six innings -- the right-hander had worked to a 1.57 ERA in six starts (40 innings) prior to Sunday. Overall, Wheeler's ERA sits at 2.56 with a 0.89 WHIP and 122:20 K:BB across 21 starts (133.2 innings) this year. He'll look to get back on track in his next outing, currently scheduled for next week at home against the Tigers.

Waldrep was scratched ahead of his most recent scheduled start with Triple-A Gwinnett on Friday and could be recalled to enter the Atlanta rotation Tuesday in Kansas City, Lindsay Crosby of AthlonSports.com reports.

While Waldrep hasn't yet joined Atlanta's taxi squad and remained with Gwinnett as of Sunday, the right-hander could still easily meet up with the big club Monday. Though the newly acquired Erick Fedde looks like a good bet to assume one of the two vacancies in the Atlanta rotation, Waldrep appears to be a strong candidate to fill the other spot on the heels of a strong run at Gwinnett of late. Over his last six outings in Triple-A, the 23-year-old has submitted a 2.41 ERA, 1.19 WHIP and 28:15 K:BB in 33.2 innings.

May (6-7) took the loss Sunday against the Red Sox, allowing four runs on five hits over five innings. He struck out five.

May looked sharp early Sunday, allowing just one run through his first four frames. However, he gave up three runs on three consecutive one-out hits in the fifth, capped by an Alex Bregman two-run homer. It's been an up-and-down year overall for May, who's given up four or more runs in three of his last five outings. His ERA sits at 4.85 with a 1.35 WHIP and 97:43 K:BB across 104 innings this season.

Gomber (0-5) was charged with the loss Sunday against the Orioles, allowing four runs on four hits and three walks across 4.1 innings. He struck out two.

It was another tough day for Gomber, who's now allowed four or more runs in three of his last four starts. The left-hander's ERA is up to 6.28 through eight starts (38.2 innings) this season with a 1.66 WHIP and 22:10 K:BB. Gomber will look to turn things around in his next outing, currently scheduled for next week at home against the Pirates.

Atlanta transferred Holmes (elbow) from the 15-day injured list to the 60-day IL on Sunday.

Earlier Sunday, Atlanta placed Holmes on the 15-day IL due to right elbow inflammation, but the club's decision to shift him to the 60-day IL suggests that follow-up tests may have revealed a more significant injury. As a result of the transaction, the earliest Holmes could return to action is Sept. 26, so his season his most likely over. The transaction will open up a spot on the 40-man roster for right-hander Erick Fedde, whom Atlanta acquired from St. Louis on Sunday and could immediately slot into the rotation. Over his 21 starts prior to landing on the IL, Holmes posted a 4-9 record, 3.99 ERA, 1.34 WHIP and 123:54 K:BB in 115 innings.
